METHOD FOR DECOMPOSITION-TREATING ORGANIC HALOGEN COMPOUND AND DECOMPOSING DEVICE

摘要

A produced gas produced by a decomposition reaction between an organic halogen compound and steam is neutralization-reacted with an alkali liquid and left for a preset time, and the neutralized product thus produced is precipitated in an alkali liquid for removing. A removing pipe (71) for pumping up the entire neutralized product is allowed to project into an exhaust gas treating tank (41), a disk-like plate (71a) is fixed to the tip end of the removing pipe (71) in parallel with the bottom surface of the tank (41), and the tip end of the removing pipe (71) is opened at the center of the lower surface of the plate (71a), thereby enhancing a solid-liquid (neutralized product-alkali liquid) separation efficiency and reducing a residual amount of the alkali liquid to be disposed of along with the neutralized product as wastes.
